Filed: 2005-01-07
Abstract: The object of the present invention is to provide a composition which is effective in retarding or preventing the development of energy decrease, appearance change, etc. of humans and animals due to aging, and is highly safe even with a long period of taking. The present invention relates to an antiaging composition which comprises reduced coenzyme Q as an active ingredient. By feeding mice which develop the aging symptom early (aging-accelerated model mice) with a feed containing reduced coenzyme Q10 for a long period of time, aging process was prevented and retarded. Furthermore, aging-accelerated model mice fed with reduced coenzyme Q10 for a long period of time showed no toxic symptom, thus it was found that the antiaging composition comprising a composition containing said substance can be made into a safe antiaging composition capable of being taken for a long period of time.
